What is bit by bit copy and when need it?
The bit-for-bit copy of a hard drive is a copy where each bit of that copy is identical to the corresponding bit in the original disk. It is also called a sector-by-sector clone. This copy method will clone all sectors no matter they are used or not, even if the sector is blank or has a logically bad sector. So, the destination hard drive is exactly the same as the source hard disk and keeps identical properties such as drive status, drive size, drive letter, the number of volumes, etc.
This bit-for-bit hard drive copy method will be quite necessary and useful when you want an exact look of the old disk on a new disk, or you need to clone hard drive with bad sectors. Next, we will show how to copy a hard drive bit-for-bit.
